I dont think that 12 year olds should be allowed to watch M rated movies because some 12 year olds watch these movies and they think that it is alright to do some of the things that were in that movie. Then they start to act like that character and they do the things that they saw on that movie. People get hurt when kids make the wrong decisions about the movies that they watch.
Other M rated movies include swearing, sexual themes and violence. Swearing should be heard from 12 year old mouths until they are older and more mature.
12 year olds should not be allowed to watch M rated movies.
